Pouch packaging is a widely utilized solution across industries, including pharmaceutical, medical device, and food sectors, due to its convenience, versatility, and cost-effectiveness. However, the integrity of seals in pouch packaging is a critical parameter that directly impacts product quality, safety, and shelf life. Ensuring seal integrity requires advanced testing methods capable of detecting even the smallest defects, such as pinholes or weak seals. Among these methods, Airborne Ultrasound Technology has emerged as a highly effective solution.

What is Seal Integrity Testing?

Seal integrity testing is a non-destructive testing method used to verify the quality and strength of seals in packaging. It involves assessing the packaging's ability to maintain a hermetic barrier, ensuring no leakage, contamination, or compromise to the product within.

Seal integrity tests evaluate factors such as:

• Presence of pinholes or microcracks.
• Uniformity of the seal.
• Ability to withstand environmental stresses like pressure and temperature changes.

Why is Seal Integrity Testing Important Across Key Industries?

Pharmaceutical Industry

In the pharmaceutical sector, pouch packaging is used to contain sensitive drugs, powders, and diagnostic kits. Seal defects in this industry can lead to contamination, loss of efficacy, and regulatory non-compliance. Ensuring seal integrity is vital for maintaining sterility and adhering to stringent quality standards like cGMP.

Medical Device Industry

Medical devices often require sterile barriers for implantable devices and products to ensure patient safety. Defective seals can compromise sterility, risking infections or device malfunction. Seal integrity testing helps manufacturers meet ISO 11607 and other regulatory standards.

Food Industry

In the food industry, defective seals can result in spoilage, contamination, and reduced shelf life. For perishable items, maintaining airtight seals is essential to prevent the growth of pathogens and ensure product safety.

Seal Integrity Testing Using Airborne Ultrasound Technology

PTI has revolutionized seal integrity testing with Seal Scan (Offline) and Seal-Sensor, both of which utilize non-contact airborne ultrasonic testing technology. With these advancements, Airborne ultrasound technology has been proven to be the most effective method for non-destructive seal integrity testing, whether in offline laboratory testing for seal quality analysis or 100% inline testing on the production line.

Seal integrity is a cornerstone of quality assurance in pouch packaging. Its significance spans industries like pharmaceuticals, medical devices, and food, where product safety and compliance are non-negotiable. Airborne Ultrasound Technology is setting new benchmarks in seal integrity testing by offering non-destructive, precise, and efficient solutions.

By integrating this advanced testing method, manufacturers can not only enhance the reliability of their packaging but also strengthen consumer trust and regulatory compliance. Embracing innovative technologies like Airborne Ultrasound is a step forward in ensuring the highest standards of product quality.

Sealer validation is integral to ensuring the reliability of medical device packaging, yet it is often perceived as complex and time-consuming. This process involves extensive parameter development, installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ). Adding post-validation process verification further increases the complexity, as well as the need for long-term reliability. Each stage of sealer validation and verification comes with unique challenges that demand complementary and precise test methods to assess the quality of sealed packages.

Why Seal Quality Matters?

Seal quality is critical for ensuring the safety and efficacy of medical devices. Traditional inspection methods often fail to address the combined importance of seal consistency, strength, and integrity, creating potential quality gaps.

Heat-sealed packages for sterile or sensitive contents must meet stringent standards to maintain sterility and prevent contamination. Advanced inspection methods like vacuum decay or helium leak detection help ensure seal reliability and regulatory compliance. High-quality seals are essential for patient safety and maintaining product performance throughout its lifecycle.

Leveraging Deterministic and Non-Destructive Testing Technologies

A common misconception about adopting advanced technologies like deterministic and non-destructive testing (NDT) is that they involve significant costs and operational complexities. In reality, these technologies—particularly airborne ultrasound—offer a streamlined, cost-effective solution for validating heat seals without compromising on quality or efficiency.

Airborne ultrasound technology provides accurate, non-destructive inspection of sealed packages, enabling the detection of defects such as channel leaks, weak seals, or inclusions. By offering deterministic results, this method eliminates subjective interpretations and enhances confidence in the seal quality.
